The issue has been resolved.Below are the details
Below I have summarized the problem faced in QAS, attempts made for solution and root causes:

1) The Last successful backup was on April 11,2011 before the kernel upgrade.2) As, SAP recommended in ‘Early watch Report’ for Latest patches and Software , So we did Kernel Patch Level Upgrade from 274 to 347.3) Now, the issue started. Since last successful DB(database) backup was on 11th,April,2011 and since Tablespaces were kept in BACKUP MODE, the (Online +redo)/full backup/Online backup was failed and archives got filled. This is root cause for the failures.

4) SAP Backups are usually taken in Tapes/disks. SAP uses Net backup (3rd party tool)utility files for getting Database backup using backint. During the Kernel patch upgrade, the permission of file /sapmnt/QAS/exe/backint was changed to root/other from qasadm/sapsys by Oracle. This has a link to a file in another location /usr/openv/netbackup/bin/backint. We are not certain on who or how the backint file got replaced here with a 0 bytes file which was the cause for failure.

5) This was noted and configured the files that are similar to PRD Server(Production).

6) The Backup(Online redo log processing) was triggered and started successfully. This got started at 10:52:18 and completed at 13:21:05. Later, offline redo log processing(Offline redo log processing)was triggered and completed successfully.
